Hello folks, I've recently bought a second hand PC with these specs:

i5-4670
H60 Watercooling
MSI Z87-G43
G-Skill 8GB 2133Mhz
ASUS HD 7770 2GB
500W Coolermaster PSU

I Like it a lot, use it for gaming. My friend has offered me his old GPU which is either another 7770 or a 7750 (can't remember) and I fancy trying to crossfire the 2.
I've read that Coolermaster PSUs ain't all that really and don't want to blow anything up - but the ************ estimated wattage for the crossfire system is about 370....sooooo what do you think? I intend on upgrading the card later anyway but thought this might be a nice little upgrade in the meantime especially since it's a gift. I'm not too sure about upgrading the PSU though, seems to have a lot of connections and stuff. I'm a bit nervous about blowing up my new toy.
 
Hmmm getting complicated.. :)

It seems I'll have to upgrade the PSU anyway when I come to upgrade, was thinking along the lines of a GTX 760 at least, so perhaps I should get it out of the way now. Changing 1 component at a time seems far more doable and less scary.
 
Thanks for the advice Danny. I was checking the Power and energy rating but not the number of PCI-e connectors so that's saved me doing something dumb. Presumably if I can find one with 4 that will future proof me in case I ever want to crossfire 2 more powerful cards?

I'm aware that crossfiring is more of a hassle and can produce problems, but the real reason I'm considering it is because I have this card sitting around being unused. I wouldn't have bothered to buy another for the sake of crossfiring, but if it's there... I wasn't planning on buying another card for perhaps a year or so, if I can squeeze more performance out of this PC by upgrading the PSU (necessary anyway by the sound of it) and sticking the spare in then I think I might. :)
