My 700 watt OCZ just died, so I am in need of a new PSU. My system is: AMD Phenom II X4 955 clocked at 3.50 GHz, 8 GB DDR3 RAM, 4 HDD's, a optical drive and an Nvidia Geforce GTX 260. I really need to get a new power supply soon, but I really do not know much about the different brands. I am not sure how many watts I need, but with the OCZ 700, I had to run a supplemental supply just to power the GPU (12V). Any recommendations would be appreciated! I will want to use Newegg if possible, because I have an account with Shoprunner that gives me free shipping!

700W is good, but you dont need that much. Im pretty sure with your setup a 600W would do you fine, but to be on the safe side I would recommend at least a 650W.

I like these :D

The OCZ 700 did not have enough power output on the 12v rail to properly power the GTX260. I ended up purchasing a supplemental PSU to provide the GPU with enough power. Now when I look at the PSU's, what do I need to have on the 12v rail to power the GPU?

Who makes your gpu card? I know its GTX260, but does eVGA make it? etc..?

XFX.

Hi,

NZXT is a brand that seems over looked but is highly rated. I am really happy with my NZXT 850w Gold, which I bought as they where out of Corsair products.

Nice! I have an nzxt case! The 850 gold is selling for $169.99 which is a bit high, but may be worth it!

For your GPU as long as you get a PSU with at least 2 x 6 Pin power connectors you are good.

I would recommend now to stick with at least 700W, but go for 750W-800W

Edit: oh and enough connections for your hard drives.

I have a Cooler Master Silent Pro 850w and it has been running 24/7 for more than a year without any issues or noise.

It is modular and can help you with that pesky cable management inside your case.

It's selling on NewEgg for $139 http://www.newegg.com/Product/Product.aspx?Item=N82E16817171048

The 700w version is $10 cheaper but I don't see any benefit for that little difference.

I have that exact same one, and it's an excellent PSU. Very satisfied. :yes:

Hello guys,

Recently I've checked the hardware monitor in bios and the numbers were:

  • CPU Voltage: 1.184v
  • 3.3V Voltage: 3.360v
  • 5V Voltage: 5.136v / 5.160v
  • 12V Voltage: 11.872v / 11.928v

So, after these numbers, you can see that 12v is lower than 12.

Should I change the PSU? If yes, can someone recommend modular Cooler Master PSU (because market in my country) for my configuration?

Future Upgrades: SSD (OCZ Vertex 4 128GB) and new GPU (ASUS HD 7850 DC2 2GB / Gigabyte GTX 660 Windforce OC 2 GB)

Configuration:

Core i5 750

Asus P7H55

2 x 4GB DDR3 1333MHz Kingston HyperX

1TB WD Caviar Green SATA2

KFA2 GTS 250 1GB

DVD-RW LG 24x SATA

PSU: Hantol 720W (Real Power: 375W)

The ATX spec includes a 5% tolerance, so as long as you are between 12.6V and 11.4V, you should be okay. Plus the software programs that read those voltages aren't super accurate to begin with. You'd have to physically check it with a multimeter.

If you're looking for a new PSU, this is the one I have, and it's rock solid:

Thank you for the info.

So, I can go with the SIlent Pro PSU's.

850W - isn't a overkill for my config (including the future upgrades)?

It probably is a bit overkill. But if you someday want to run crossfire or SLI, you'd be happy you had the extra PSU headroom.

When I was running 570s in SLI, the 750W I had at the time, really struggled.

If you're on a budget, I'd say yeah it's unnecessary. But if you upgrade it now, it's one less thing to upgrade later.

    • Valve finally confirms Steam Machine prices, starts at $1049 for 512GB option

      Those are some popular multiplayer games. But hardly "all". Just those that don't work on Linux currently due to specific anti-cheat implementations. I think it's also fair to point out the literally thousands of games that don't work on the PS5. And it's not locked at 1080p. That's the default, which you can change.
    • Ubuntu Livepatch arrives on Arm64 to eliminate system reboots for kernel updates

      By zikalify · Posted

      Ubuntu Livepatch arrives on Arm64 to eliminate system reboots for kernel updates by Paul Hill Canonical has just announced that its Livepatch service now supports computers with Arm64 processors. For those who are not familiar, Livepatch allows users to apply important kernel updates without any service interruption or rebooting. While home users will benefit from this, it’s even more important for critical machines that absolutely should not be going offline at all. The feature is available as part of Ubuntu Core 26 for Arm64 and Ubuntu Core 20 and onwards for AMD64. According to Canonical, this will improve the security of systems that aren’t security-maintained daily or weekly, and it helps organizations work towards Cyber Resilience Act (CRA) compliance. If you are familiar with Ubuntu, you probably know that most packages can be updated without having to restart the system. There is one big exception to this, and that’s the kernel; it typically requires you to reload the system to boot into the new kernel. With Livepatch, Canonical has done something so that you don’t need to restart to begin using the new kernel. Aside from Ubuntu Core 26, users with Arm64 chips running Ubuntu 26.04 LTS can also use Livepatch. If you want to learn more about Livepatch, check out its product page. There, you can also find a button to join Ubuntu Pro (it’s free for several home devices) so that you can enable Livepatch. By linking your computer to Ubuntu Pro, you will also extend the life of your Ubuntu install from five years to ten years. If you are running Ubuntu, let us know in the comments if you have been looking forward to this feature on your ARM-based computer. If you’ve had a compatible AMD64 machine for a while and never used this feature, let us know why in the comments!

    • Meta announces a major leadership change at WhatsApp

      By pradeepviswav · Posted

      Meta announces a major leadership change at WhatsApp by Pradeep Viswanathan Meta has announced a major leadership change at WhatsApp, with Will Cathcart stepping down after seven years of leading the world's largest messaging platform. CRED CEO and founder Kunal Shah will take over as the next global head of WhatsApp. CRED is an Indian fintech company focused on creditworthy consumers. As part of the transition, Meta is also making a minority investment in CRED through its Series H funding round. Meta CEO Mark Zuckerberg said Will Cathcart will remain at Meta and move into a new role focused on building new products from the ground up. Cathcart led WhatsApp during a major growth phase, helping the app reach more than 3 billion users worldwide. He also played a key role in expanding WhatsApp’s business offerings while keeping privacy and end-to-end encryption central to the product. Meta’s Chief Product Officer, Chris Cox, said Kunal Shah was selected after a search for a leader who understands WhatsApp’s global scale and future potential. In a leaked internal memo, Cox described Shah as a “serial founder” and one of India’s most respected entrepreneurs, adding that he brings “entrepreneurial energy” and a strong product mindset to the role. As part of the Series H funding round, CRED is raising ₹8,550 crore, or about $900 million, in a round led by Meta. The funding values CRED at ₹43,239 crore, or about $4.5 billion, on a post-money basis. It is important to note that this investment will not give Meta access to CRED customer information. Kunal posted the following on X regarding his new role at Meta: Although Kunal Shah will be stepping away from his operating role as CRED CEO, he will retain his personal shareholding in the company.
    • It's about to become harder to turn off your Samsung TV, thanks to Instagram

      By fishnet37222 · Posted

      It wouldn't be hard for me to turn off my TV, if I had one. For one thing, I never scroll Instagram. The only reason I have an account is because Meta created one when it merged the account systems for its various services.
