First off, your selected PSU isn't in this vetted
recommended PSUs list. You'll notice that only Rosewill's 80+ Gold/Platinum units are listed. Not quite sure what your PSU budget is but the
CX 430 v2 $25 ater $20 MIR is an excellent choice for tight budgets. According to
this PSU calc, your build should consume 325W without overclocking and 400W with max overclocks (over 40% CPU overclock and overvolted GPU). If you'd like a higher wattage unit, you can select 500-600W units from the list.
According to
this guide on computer components, HIS is an 'ok' manufacturer. If your budget allows, I'd go for a higher quality brand (ASUS, MSI, Gigabyte, XFX Sapphire).
