Helloo

anyone used : OCZ Technology PSU, ModXStream Pro, 700W ?

After I ordered it, I read a mix of reviews, actually most reviews were okay/good, but after reading the HardOcp test on it, and it failed I am kinda worried now.

Anyone used this one before? Can it run a i5 3570k and a AMD 7870 , on a MSI Z77A-G45 Board? they are stock but after building it I would love to overclock them.

Should I cancel my order and try find a better psu? any suggegstions? here in the uk this weekend will be a public holiday, and i thought to start building everything tomorrow, but I am just worried about this psu? Should I not be worried and go ahead and build tomorrow or cancel, and wait for a new one to arrive for next week?

Thanks

It failed at high temp operation. At normal/moderate temps it did 'OK'.

What's the cost of paying to return that item? It's always best not to open the packaging.

Its not the best model, but its not a terrible unit that is going to fail you. Go ahead and use. Your concerns really only come into play with crossfire-type loads.

As far as I'm concerned the major problem with the OCZ ModXStream Pro 700W is that there is no reason to buy it over the 600W version, unless maybe it is cheaper. This is because it is 50W more powerful on the 12V rail, and there is no difference between them in terms of functionality/cable configuration.

no need to worry, they re-tested it and it passed (see the link). its a solid PSU for the money and you won't be pushing it with your set up even with OC (see the chart)

At the time we wrote the original review of the ModXStream Pro 700w, the packaging for this unit clearly advertised that the unit was rated at 50c and as such we commented on the unit's failing performance as, from what was provided to us at the time, the unit was under-performing by the manufacturers guidance not just our testing standards. However, after the unit’s failure we were informed that the unit is actually rated at 40c (not 50c) and the current packaging we have in hand does indeed now indicate this rating. So today, we have retested this unit at 40c and found that, yes, the unit is capable of full power in specification at 40c. With our original review there is no doubt a large part of our negative impression of this unit was due to the fact that we had what appeared to be a unit failing at 5c UNDER its advertised temperature NOT the reality of having a unit failing at 5c ABOVE its rated temperature.

I have the 500W version of your PSU running an AMD Phenom II X3 720 BE and an HD 6850 with absolutely no issues. The 500W version of this PSU is actually sufficient for your rig unless you plan on SLI.

Hi guys ,

thanks for all the replies , I am not thinking of running cross fair now, as I believe the 7870 will be fine alone for some time .

I could have got a better quality 600 watt but after your guys views I am gonna stick with this one,

Lol while I am writing this post it arrived.. Thanks a lot for the replies guys really appreciate it.
