5770 on 375W

I got the HIS 5770 1gb from newegg.com along with a 460W coolmaster psu. The psu was defective. I put my stock psu from my dell xps 420 and it works. The recommended wattage from the 5770 is 400W.. I am curious if I can use the stock psu- which I think is 375W- to power the card while running games in the interim.

I have no intensions of overclocking.. does anyone have any recommendations for a psu that is $50 or less? I am somewhat skeptical to get the same one since it didnt work right out of the box..

  1. As long as it is the 375W unit you'll be just fine, Dell branded PSUs give a very high proportion of their output on the +12 volt line-just where it's needed-instead of wasting Watts on the +3.3 and +5 volt lines.

    Others will, no doubt find something classier but this is still a fine, if basic unit for the money:

  2. I tried to do the exact same thing with a lower than recommended PSU and things were OK for about a week, then for some reason or another my PC started rebooting at random and it was inevitable I had run out of time ... I paid $65 for a Thermaltake Black Widow 550 and never had another problem with the power.
  3. Thanks guys. I was thinking about just returning it.. But I guess I will just get a exchange. Too bad some of the damn cables are too short. Wish it came with extensions..
  4. THe Antec NEO ECO 520 is only $59 with free shipping at newegg - so about $5 more than the one Coozie7 listed and is 80+ certified.

    The Coolermaster does a max of 26 amps on the 12v rails according to the label, the Dell 375 can put up to 30 amps of it's power there. You would be fine for more than just the interim.

    That's a 7.5 total , not that it matters

    Here's a glowing review of the Neo550

    Here's a good review of the Neo430

    None of these are the new NeoEco 520 watt model, there's no way of knowing it's quality by reading any of those review's.
  8. 375 Watts will probably work, but it will put a strain on your system.

    Here is an inexpensive power supply that I've used several times...
