Best 750W PSU

Kev_19 · 31 May 2010 at 23:47

Ok so my BeQuiet 750w PSU has failed after 1 year, so I need a new 750w PSU. I don't want to spend too much - read Seasonic X-750 750W - but I also don't want to end up with a cheap 750w PSU with a poor efficiency rating.

Any suggestions please?

Never heard of a problem with the reliability of CM PSUs.

I know it is not 750w, but I am guessing that you don't even need 700w.

I bought my psu (see sig) as it was on TWO for the same price as the 650w version at the time. I estimate my rig using no more than 450w full load. To use 700w+ you must be using two high end video cards and a bunch of hard drives.

Sorry I meant to say it has to be a modular PSU.

Thats my spec

Intel Core i7 920 D0 Stepping
Asus ATI Radeon HD 4890 1024MB GDDR5
Gigabyte GA-EX58-UD3R
OCZ Gold 6GB (3x2GB) DDR3 PC3-12800C8
Western Digital Caviar Black 640GB SATA-II x2
Creative Sound Blaster X-Fi Xtreme Gamer 7.1

I tried a few PSU calculator sites and they all said to go for at least 700w PSU. Even when I was getting suggestions on his forum for my pc build last year I was told to go for 700w

Even with your cpu at 4ghz a 500w psu would run that fine.
Brother is running an i5 750 (stock atm as wants a new psu) and a 5870 on a 480w psu without issues. He is getting a new one soon though.

If I were you I would get a decent brand psu that is silent. If you get one that is 600-700w then you have some room for upgrades in the future

Why does it have to be modular? It's really just a commodity you can do without if on a budget.

Any reviews of that PSU yet?

This. Can get so messy in the case.

Haven't looked tbh, however I would be absolutely amazed if OCZ released a psu that was not decent!

Was thinking the same. Might wait and see what is said about it in reviews 1st. Have RMA'd my old psu so want to look at other options since its no longer on the market.

Are you willing to spend £100 on a power supply unit, Kev_19? If so, the Corsair HX 650W ATX Modular SLI Compliant Power Supply should suit your needs just fine. A review of the unit can be found here.

I would look at the Antec TruePower New 750W:

http://www.overclockers.co.uk/showproduct.php?prodid=CA-116-AN

http://www.overclockers.co.uk/showproduct.php?prodid=CA-115-AN

It is made by Seasonic and has high efficiency.

Some reviews of the PSU:

TBH, the 650W version of the Antec TruePower new would be fine IMHO:

Here is a review of the PSU:

http://www.bit-tech.net/hardware/psus/2010/02/22/600-700w-psu-review-round-up/7

Many of the higher end OCZ PSUs are made by FSP and Sirtec. Seasonic is a better OEM and they tend to use better quality capacitors.

Looks good alright. The be quiet 750W psu cost me £105 so don't mind if it came as a direct replacement. Have to wait and see what OCUK say when they check my faulty one 1st.

Isn't that covered by warranty?

A good quality 500w PSU would be more than enough!

. . maybe 600w if you ever intend to go Crossfire!

or for a tenner more you can get the modxstream 700w which runs my pc fine and dandy and probably would yours

There are -plenty- of budget modular PSUs on the market, not choosing one on purpose is just silly.
