Spotted this on the TodayOnly Page under Super Savers, seems a pretty decent price especially for a 90% efficiency rating and modular power supply. Features a 135mm Fan and is SLI/CrossFire Compatible as well.

Also if people are interested the 600W version is available for 71.99, remember to go through the TodayOnly page.

Here is some more information for people relating to the sound levels and efficiency levels.

EDIT

Now changed to £80.39 instead of 83.89.

Cheapest gold rated PSU I've seen.

Yep, next cheapest available is from Ebuyer at £93. Based on the reviews for it they seem to be very quiet and excellent performers. Ordered one myself to replace an awful cheap PSU that came with a pre-built PC my girlfriend bought about two years ago.

90% Efficiency means super hot post.

shows up as 93??

You have to find the link in the deals of the day page and click that. If you search for it using the search function then it will come up as full price...

scan.co.uk/Tod…spx is a better link - £83.99 is further down. Delivery charge on top unless you're an AVForums member.

The 0.9 power factor is only when the PSU is running under it's most efficient current draw (between 40% and 60%)

Isn't this true for all PSUs that quote power efficiency levels?

Edit: Oh, wait, I see what you're saying. These PSUs are rated at "80 PLUS", so they say "90% Efficiency", but that doesn't mean the same thing as "90 PLUS".

Edit 2: There are other PSUs available on Scan's Today Only page from Coolermaster as well, so if you don't need 700w (Most people don't unless they're running a powerful gaming computer), then drop down to a 600W or 500W and save money.

According to the Coolermaster product page, the lowest efficiency is 88.5% and the highest is 92%. Still pretty damn good.

This exact model was £76.79 at scan over the weekend on today only. I should know as I ordered one. I get free delivery as a member of the bit-tech forums.

The most noticeable thing for me is that running a 3d game my power draw dropped by 40watts compared to my old generic PSU. I guess this is to do with the efficiency of this supply.

Running an intensive 3d game my rig draws only 200 watts (using an ATI 6950 card so you could argue 700w is overkill

£80.39 now

You don't mean power factor - that's a term used to describe current lag (or lead) due to reactive components of a circuit.

if u think this is a good deal, then u may wanna check the aria forums!!

the stock guys there have confirmed that they are going to start stocking a 1KW Mushkin Joule Modular PSU for £69.99!!

myself, i would go for the £59.99 600w version tbh :)!

psu noob here, can someone please explain why this is better than a bog standard 500w coolermaster psu? with this one being 90% efficient, and assuming the 500w one being say 70% efficient, i'm just drawing less power and hence saving on electricity costs (assuming all other components are the same)?

if ur 500w bog standard works, then u dont really need to upgrade.

this being more efficient will pull less power from the wall.

it will also allow u to add more things to ur pc in the future like a high powered graphics card or hdd's etc. whereas that bog standard 500w may not be good enough to power the high end graphics card or lots of hdd's.

this is also modular, meaning u only use the cables u need. this helps to reduce cable clutter in ur case and gives better airflow.

hope this helps :)!

went for the 500w, thanks for the sort of heads up.

thanks. am contemplating buying this so that i can upgrade my whole rig to a sandybridge cpu and mb. atm my pc is causing me major headaches with random freezing and bluescreens, dont know whether its the cpu (phenom x2 940), the ram, the motherboard itself or the psu.

pcs can be a right pain in the ****

lol!
best get an SSD then :p!

Also, my little npower smart monitor thingy is telling me I'm using up to 400w less power than my rubbish old maplin gtx 480w which must have been operating at the full 480w constantly. Should pay for itself in no time at all.
